WASHBOILER.

Application filed June 6, 1927. Serial *No. 196,784.

This invention has reference to a clothes boiler, the primary object ofthe invention being to provide means for boiling and simultaneouslywashing the clothes positioned within the body portion of the device,eliminating the use of mangles or other turning or mixing devices,thereby reducing the wear on the clothes or articles being washed to theminimum during the washing operation.

Another object of the invention is to provide a device of this characterwhich may be operated to accomplish its purpose slowly or quickly undera great degree of heat.

A still further object of the invention is to accomplish the washing ofthe clothes simultaneously with the heating of the water in which theclothes or materials are positioned for washing.

llith the foregoing and other objects in View which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawings:

Figure 1 is a vertical sectional view through a combined boiler andwashing machine constructed in acordance with the invention.

Figure 2 is a vertical sectional view taken at rightangles to Figure 1.

Figure 3 is a transverse sectional view taken on line 8-3 of Figure 1.

Figure 4 is a sectional view taken on line 44: of Figure 1.

Referring to the drawings in detail, the device includes a boiler-likebody portion indicated generally by the reference character 5.

Secured within the body portion and arranged at the bottom thereof, isan elongated plate 6 that is bent intermediate its side edges providingan air passageway throughout the length of the bottom of the bodyportion, when the edges 01 the plate are secured to the bottom in amanner as shown by the drawings.

Openings 7 are formed in spaced relation with each other and disposedthroughout the length 01'? the plate so that air is forced outwardly andupwardly agitating the water and clothes or materials under treatment.At

one end of the body portion is secured a vertical pipe 8 which hasitsupper end disposed adjacent to the upper end of the body portion, thelower end of the pipe extending to a. point at the bottom of the bodyportion where the pipe communicates with the air passageway through theopening 9, to the end that air 7 entering the pipe 8 may be directed tothe air passageway.

It is to be understood that a suitable pipe not shown and leading from asourceoi' air supply is connected with the pipe 8 to direct air to theinterior of the body portion.-

As illustrated by Figure 2, the upper extremity of the body portionextends doWnwardly as at 1.0 and outwardly as at 11, where it isinclined downwardly defining a flange to guard against the boiling waterpassing from the body portion under intense heat.

The cover is indicated by the reference character 12 and has a dependingflange 13 fitted within the top of the body portion. to secure the coverin position. Secured to the inner surface of the cover as by means ofthe flanges 14l,is a condenser plate 15 which is concaved as shown, thesame being provided with openings 16 formed at the center thereof sothat the condensates may be returned to the boiler, thereby greatlyrelieving the pressure of steam within the body portion'while the deviceis in operation.

It might be further stated that the member 15 is of a shape to conformto the shape of the cover of the device, the edge thereof being,

disposed above the inwardly extended extremity 11 so that the steam inpassing upwardly must pass around the inwardly extended portion llandinwardly over the member 15.

A substantiall small onenin indicated at 17 is provided in the cover andrelieves to a degree, the steam pressure in the holler.

The reference character 18 indicates a hanair passes through the waterand clothes or articles being washed agitating the clothes and water tothoroughly clean them.

From the foregoing it will be seen that the cleaning operation isperformed simultaneously with the boiling of the clothes.

I claim: r

A wash boiler including a body portion, the upper edge of the bodyportion being bent downwardly and inwardly defining an inclined innerflange a cover having a flange fitted within the body portion, acondenser plate secured to the cover, means for securing the condenserplate to the cover to hold 7 the edges of the condenser plate'in spacedrelation with the cover to permit steam to pass upwardly therethrough,said condenser plate being bulged downwardly at its central portion andformed with openings to allow condensation to pass therethrough, and theedge of the condenser plate lying-above the cen tral portion of theinclined inner flange.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature.

Y JOHN ABRAM DUNHAM.
